EXCLUSIVE: 'This Is Us' Star Milo Ventimiglia Warns Final Two Episodes of Season Will Be 'Stressful'

With only two episodes left in This Is Us' first season, the drama is ramping up.

ET caught up with series star Milo Ventimiglia, who plays patriarch Jack Pearson, at NBCUniversal press day on Thursday, where he warned that the remainder of the beloved drama’s freshman run is about to leave viewers on the edge of their seats.

“Get ready, it’s going to be stressful,” the 39-year-old actor, still rocking an arm sling following a recent surgery, told ET at New York City’s Four Seasons Hotel.

If the most recent episode, which ended with William’s (Ron Cephas Jones) death, broke your heart and had you hugging your loved ones, Ventimiglia warned, these next installments will wreak havoc on your anxiety levels.

“Where William’s passing in episode 16 broke you open, there’s a lot of emotional repair you need after that episode. These next two [are] just going to stress you out,” he added.

Though Ventimiglia kept finale details close to the vest, he hinted that there will always be an element of hope, no matter how dire the circumstances may seem.

“[Creator] Dan Fogelman has a genius way in his writing where he’s tackling all of these issues and he’s breaking down the emotional response to things that we all experience, but never leaves you hopeless,” he said. “Even though things may be crumbling or in disrepair or up in the air, the skies will part, the clouds and the sun will shine again.”

“I think people need to put away their desire to know and be satisfied with that and know that it’s coming,” Ventimiglia promised. “It could be the next episode. It could be the second to last episode. It could be a ways away.”

“But I think the idea is [to] embrace the moment that we’re in and know that it’s coming. You gotta be ready for it at any given time,” he continued. “It could very well be this season. You never know, you never know.”
